2 Claims.

My invention consists of apparatus for cooling,

conditioning, purifying and Ventilating dwellings, factories, assemblyhalls and the like, by apparatus without moving parts, operated solelyby differences in the speciic gravity of the air in different parts ofthe apparatus. My invention is carried out by causing said air to flowthrough regions in which it is cooled and purified before beingcirculated throughout the building. The apparatus also includesprovision forstorage of cooled air prior to its use to insure anadequate available suppl Apparatus adapted to carry out my inventionwill consist of a cold storage chamber with communication to the outsideair, and to a conduit or conduits extending through the interior of thebuilding so that air used for ventilation will be cooled by passagethrough this chamber.

v Whena beam of sunlight is permitted to enter a room from which otherlight is excluded myriads of otherwise invisible particles are seen sfioating in the air. These ilcating particles consist of many kinds ofsolid matter` some quite harmless while others are disease germs ofvirulent type.

When air containing such dust particles is cooled down to a temperatureat which moisture tends to condense, each of the floating dust par- Yticles becomes a nucleus and attracts molecules 30 or moisture, orsuchparticles are'bombarded by molecules or atoms of the vapor andbecome coated with a film of moisture which increases the weight of theparticle so that it tends to fall by gravity; the falling particlescollide and coalesce with others and finally form drops of water whichfall to the earth as rain. After such a shower the air is noticeablyclean and pure.

I effect removal from the air of all dust, disease germs and the like bycarrying it' through 40 a cold storage chamber in which moisture iscondensed, repeating within the apparatus the phenomena above described.

The cold storage chamber may be located below ground,- above the roof ofthe building or in any intermediate position.

` The drawing illustrates a cold storage chamber CSC" locatedoutside thebuilding B" which is to be ventilated, and at a yheight midway betweenthe second yandthird oors and having a capacity to hold four v(4) 300pound cakes of ice. A ramp for illing the chamber with ice is indicatedby the dotted line vA trap T" is provided for the discharge of ice waterand condensed moisture from chamber CSC". The intake conduit CC" extendsabove the roo! of the building and (Cl. (i2- 26) is equipped with arevolving hood with ,vane to keep it facing the direction in which thewind is blowing thus assisting the circulating of air through CC, CSCand the cold air conduit CAC with valve controlled outlets in the base-5 ment.

The air in the distributing conduits-DC, DC, becoming warmed from theheat of the building, by its buoyancy gradually draws up the cold airaccumulated in the basement, aided by the pressure of the downwardflowing cold air in CAC, and distributes it to the second and thirdfloors, the building thus being supplied with dry cool air which is ofaseptic nature and which, upon becoming warmed within the building, willabsorb moisture from damp walls of the interior of the building .thusimproving its condition both as to comfort and health of those employedor living therein.

A valve controlled discharge from the upper floor through the hoodedoutlet X provides for the discharge of air contaminated by theexhalations of persons and animals, odors from materials beingfabricated, treated, ironed, fromA machines or chemicals used, etc. 25

The arrangement of conduits may be varied widely from those shown by thedrawing without departing from utilization of the laws controlling thecirculation of liquids, fluid gaseous mediums such as air, steam andvapor through conduits, and the rate of ow may be directed andcontrolled by adjustable valves to regulate the quantity of ventilationdesired to be utilized inthose parts of the building to be ventilated,

' as will b e understood and readily used by those 35 familiar with theart.

Any room in which no ventilation is desired is closed oi to theventilation system by the valved outlets of the drawing. Cold air whichhas accumulated in the basement is in readi- 40 ness for delivery to anyroom in which ventilation with cooled air is desired, immediately uponthe valved outlet to that room Abeing opened'.

The structure shown by the drawing is intended to be diagrammatic andreplaceable by 45 other equivalent devices by which similar or identicalfunctions can be performed.

The present application is a continuation of the abandoned applicationSer. No. 713,673, filed by H. M. Chance on March 2, 1934.

In the following claims, I have further described my invention:

1. The combination with a building having a basement and upper rooms tobe ventilated, of apparatus for eifecting ventilation comprising acooling chamber disposed exteriorly or' the building and at a heightabove said basement, means within said chamber for cooling air thereinby contact, said chamber #having an inlet opening through which externalair may be admit-ted thereto, and having an outlet opening through whichcooled air may be discharged, a conduit connecting the outlet openingand the basement of the building for discharging-cooled air into thebasement for storage, and a conduit connecting the basement with theupper rooms of the building to be Ventilated, said last named` conduitopening into the basement at the lower portion thereof and apart fromthe point at which the conduit from the cooling chamber discharges intothe basement, the elevated position of said cooling chamber forcingcooled air into the basement by gravitational action and thence upwardlyinto the rooms.

24D 3. The combination with a building to be ven'- tilated, of apparatusfor effecting ventiiation comprising a cooling chamber, means within thechamber for cooling air passing therethrough, said chamber having aninlet opening for admitting external air thereto and having an outletopening for the delivery of cooled air, a conduit leading from saidoutlet opening to a zone spect to the lowermost portion of said zone tocause delivery of cooled air by gravitational flow of the cooled air,and an accumulation chamber interposedin said conduit between thecooling chamber and the zone to be cooled, the cooled air entering theaccumulation chamber at one point and being delivered therefromatanother peint so that cooled air flows through the accumulation chamberor will be stored ,therein prior to use.
